Title: Clock generating circuit
Inventor: MATSUBA TERUO
IPC: H03L7/08
Filed: 1987-02-27
Abstract: PURPOSE:To obtain a clock signal faster than a clock signal inputted externally by incorporating a ring oscillator and a frequency divider into an LSI, applying phase comparison to an oscillator output frequency-divided with an external clock so as to control the oscillated frequency. CONSTITUTION:A phase comparator 12 outputs an up-signal or a down-signal in response to the phase lead/lag to drive an up-down counter 15. The parallel output of the up-down counter 15 selects switchingly a selector 8, and since the selector selects switchingly the path length in a way that the path length is shorter when the clock signal of the ring oscillator 9 is retarded and the path length is longer when the clock signal is advanced, the oscillated frequency nf0 of the ring oscillator 9 is controlled synchronously with an external clock signal f0. Thus, the highest frequency signal of all the inputted external clock signals fed to the LSI is used for the inputted external clock signal to obtain a sufficiently faster clock than the clocks fed from plural clock generators to the LSI.

Title: Cooling device for video display device
Inventor: YOSHINAGA HIROSHI
IPC: H04N5/74
Filed: 1995-03-07
Abstract: PURPOSE: To reduce the temperature change attended with the change in a horizontal frequency by providing a horizontal frequency detection circuit, a cooling fan control circuit outputting a signal to control a cooling fan and the cooling fan. CONSTITUTION: The cooling device is made up of a horizontal frequency detection circuit 1, a fan control circuit 2, a cooling fan 5 and a cooled section 4. Then the horizontal frequency detection circuit 1 detecting the received horizontal frequency signal outputs a DC voltage proportional to the detected frequency. Furthermore, the cooling fan control circuit 2 receiving th DC voltage controls the number of revolutions of the cooling fan 5. In this case, when the horizontal frequency gets lower, the number of revolutions of the cooling fan 5 is reduced and when the horizontal frequency gets higher, the number of revolutions of the cooling fan 5 is increased to cool the cooled section 4 in response to the horizontal frequency. Thus, the number of revolutions of the cooling fan is changed in response to the horizontal frequency to prevent the temperature change in the inside of the set.

Title: Semiconductor device
Inventor: UCHIDA HIROYUKI
IPC: H05K3/34
Filed: 1990-02-26
Abstract: PURPOSE:To minimize a wiring length from an inner wiring of a package to a circuit substrate by forming an L-shaped outer lead terminal and by alloy- bonding one end thereof pressing a surface of an outer lead terminal attached part on a ceramic substrate. CONSTITUTION:An outer lead terminal 3 is formed to an L-shape whose length of short side part exceeds a height of a ceramic frame body 4. The short side part is made to stand vertical along a side wall of the ceramic frame body 4 and brazed so that an end of the short side part presses a surface of an outer lead terminal attached part 2 arranged on an outer peripheral part of the ceramic substrate 1. Since the outer lead terminal 3 is bonded so that an end part of a lead conductor presses the outer lead terminal attached part 2 approximately at right angles, a length (l) of the outer lead terminal is minimized. A long side part of the outer lead terminal 3 is led out in parallel to a surface of the ceramic substrate 1 from a position higher than the ceramic frame body 4; therefore, an increase of a lead length caused by bend process can be prevented.

Title: Fingerprint collating method
Inventor: IGAKI SEIGO
IPC: G06T7/00
Filed: 1990-02-27
Abstract: PURPOSE:To reject a wrong input due to a replica or the like by collating not only feature information of fingerprint but also the time series change of fingerprint depression. CONSTITUTION:The fingerprint image inputted from a fingerprint sensor 11 is inputted to a feature extracting/collating part 15 and is converted to digital data. This fingerprint image is binarized and is stored in a binarized image storage part. The binarized data is read out and is subjected to preprocessing, and feature information is extracted and is stored in a feature information storage part 14. When the fingerprint image is read out of the sensor 11, a pressure sensor set in the sensor 11 detects the time series change of depression. A depression change detector 12 samples the time series change of depression at intervals of a certain time to convert it to digital data and stores the data in an incorporated time series dictionary. The fingerprint image inputted from the sensor 11 is inputted to the extracting/collating part 15 and is binarized and is subjected to pattern matching to feature information read out of the storage part. When both patterns approximately matched for each other and time series changes of depression matched for each other, the matching of fingerprint is decided.

Title: Fuel injection nozzle for internal combustion engine
Inventor: KOJIMA TERUTADA
IPC: F02M45/00
Filed: 1986-03-06
Abstract: PURPOSE:To reduce an injection rate on the initial stage of fuel injection with a simple and small structure by providing a lever which is rotatably supported on a nozzle holder with a fulcrum in between the spring seat of a needle valve closing spring and the end part of a needle valve. CONSTITUTION:In a fuel injection nozzle 1, during the initial stage of the valve opening of a needle valve 14, i.e., when the moving quantity is small, the projected part 23 of a spring seat 22 is brought into contact with a lever 25 pushing up the spring seat 22. When the pushing up quantity of the needle valve 15 gets larger, the first point of application 31 of the lever 25 is moved from the contact point in the initial stage of the valve opening to a position separated from the fulcrum 26 of a nozzle holder 2. Therefore, the reaction of the spring 19 which acts on the needle valve 15 is relatively increased, restricting the lifting up of the needle valve 15. When the pressure of the supplied fuel is further increased, the needle valve 15 again overcomes the resiliency of the spring 19, pushing up the spring seat 22 through a second point of application 32 via the lever 25. Thereby, a large quantity of fuel can be injected per unit time under a larger pressure as compared with the initials stage of injection.
